Kinematic results for the individual spectra when using different stellar-subtraction methods and line-fitting approaches for the Hα (top) and [NII] (bottom) emission lines. The four line-fitting cases and the five stellar-subtraction methods used are highlighted according to the different symbols and colors (as in Fig. 2), respectively (twenty values for each spectrum). The mean wavelength and dispersion (, ) as well as their standard deviation (, ) are represented using dashed light gray lines and the shaded area (light red and cyan), respectively.
